The new study reveals amazing curds about the start of the subdue on earth

An important geological process on the earth, the subdue can traditionally start millions of years ago.

This amazing discovery has been made in a new research published in the GFZ Helmulus Center for GeoSins, with international colleagues, published. Nature communications. The team from Potsdam (Germany), Greenobel (France), and Medicine (USA) shows evidence that the formation of the subdivision and the continent during the so -called Hadine Evan was already active and much stronger than the previous idea.

Huden Avon, which extends from 4.6 to 4.0 billion years ago, is the most passionate chapter in the history of the earth. It began with the formation of the planet, followed by a massive collision with Mars -shaped body, causing the creation of the moon and melting the inner part of the Earth. The stability of the land layer began about 4.5 billion years ago, but what happened after that is being debated.

The prevailing theory shows that at least by the end of the headian, the earth was locked in the “stagnant lid” tectonic government. In this model, our planet was covered with a tough, unmanned outer shell, under which the transport process is under the veil of the earth.

Now, researchers are challenging this view.

In its new study, the team provides evidence that the formation of a more dynamic and continental layer was already active and more powerful than the previous idea. Using an innovative analytical technique, the Greenobile team measured Strontium Isotopus and Trace elements in the melts stored within the 3.3 -year -old Olivan crystal. Meanwhile, the GFZ team used modern geodenic imitation to translate these geo -chemical signals in terms of early land process.

Their common results have been proposed more actively than the results, which shows that the idea of a large amount of subcarded and continent may begin millions of years ago.
